DCMT070208 NS9530 Tungaloy indexable turning insert — uncoated cermet, finish turning

DCMT070208 NS9530 is an ISO rhombic indexable insert designed for precision finish turning of steel components with continuous cuts and small depths of cut.

• ISO rhombic insert, size 07
• Uncoated cermet NS9530 for fine finishing
• 7° clearance angle for smooth cutting
• Cylindrical hole with single-sided countersink

High-quality finishing through cermet technology

The combination of an uncoated cermet grade and a sharp cutting edge provides markedly reduced cutting forces and improved surface finish in finishing operations. As an ISO-standardised turning insert, this geometry is produced to tight tolerances so that repeatable results are achieved when mounted in the appropriate holder. The NS9530 grade is tailored for fine turning of steel, enabling a consistent surface quality even on continuous cuts; the material’s wear characteristics are explained so that expected tool life can be assessed under typical finishing parameters.

Geometry and mounting for reliable compatibility

Compatibility with a given holder is determined by form, clearance angle, tolerance class, fixing method, size and thickness. This insert features a rhombic form, a 0.8 mm corner radius and a 7° clearance angle, together with a cylindrical hole and a single-sided countersink (40°–60°) to suit standard clamping systems. Because the dimensions follow ISO conventions, interchangeability is simplified and the correct clamp, shim or screw will ensure stable seating and repeatable indexing during production runs.

Process benefits: efficiency and surface integrity

The insert’s geometry and the NS9530 cermet combine to lower cutting forces and reduce vibration during finishing, which in turn supports higher feed stability and improved workpiece appearance. For precision components where surface integrity is critical, these characteristics translate into fewer downstream processes and more predictable throughput. Selection of an appropriate chipbreaker and adjustment of small depths of cut will further enhance process reliability and help to maximise the insert’s productive life.

Recommended applications and cutting considerations

Designed primarily for external and internal turning in steel, this insert performs best with continuous cutting and modest material removal rates. The 55° orientation supports access to interrupted profiles while maintaining a balanced cutting force vector. Typical recommendations include fine feeds and shallow depths to exploit the sharp edge and cermet’s affinity for high-quality finishes; coolant strategy and machine rigidity should be matched to the intended cycle to avoid thermal or mechanical shock to the cutting edge.

FAQ

Which materials is this insert suitable for?
The DCMT070208 NS9530 Tungaloy indexable insert is formulated for finishing operations in steel and is best used where a high surface quality is required.

Can the insert be used for internal turning as well as external turning?
Yes, the rhombic geometry and the 55° orientation allow the insert to be applied in both external and internal turning operations with proper tooling and holder selection.

What are the key geometry details to check when selecting a holder?
Check form, clearance angle (7°), thickness (2.38 mm), hole style (cylindrical with single-sided countersink) and size (07) to ensure compatibility with the chosen holder and clamping system.

How does the NS9530 grade affect cutting parameters?
The NS9530 uncoated cermet is optimised for low cutting forces and fine finishes; it performs best with shallow depths of cut and continuous feed conditions to exploit the sharp cutting edge.

Is this insert suitable for interrupted cuts?
While the insert can be used on profiles with occasional interruptions, best results are obtained in continuous cutting; assess machine stability and reduce the depth of cut for heavy interruptions.
